What clues could you use to help determine whether movement of oslutes through the apicl and basolateral cell membranes is passi

Setler79 [48]

Answer:

Clues that can be used to determine whether the movement of solutes through the membrane is passive or active could be the molecule size, membrane potential, and the presence/absence of membrane protein.

Explanation:

Solutes transport through the cellular membrane depends on the solute size, membrane potential, and the presence/absence of integral membrane protein.

There are two types of transport: Active and passive.

- Passive transport: It does not need energy; it is driven by a chemical potential gradient. Small molecules with no charge are transported through the membrane in a gradient favor, from a high concentration region to a low concentration region. There are two types of passive transport: By simple diffusion (small molecules pass through the membrane by themselves) and by facilitated diffusion (molecules are helped by integral membrane proteins to pass through the membrane). In facilitated diffusion, the helping protein can be a channel protein (hydrophilic pores that allow the molecule to pass with no interaction) or a carrier protein (proteins with mobile parts that suffer modification as the molecule pass to the other side).

- Active transport: It does need ATP energy to pass the molecule through the membrane, as they have to move against the electrochemical gradient. This kind of transport is always mediated by a carrier protein. These proteins join with the molecules and suffer changes as they pass the solute to the other side of the membrane. An important example of this kind of transport is the sodium-potassium bomb.

The lysosome functions in a cell like the _______ does in our bodies.

Troyanec [42]

Lysosomes remove waste at a cellular level.
They contain digestive enzymes, so they're like the digestive system.
The stomach digests food, so lysosomes could be considered like the stomach.
But then again, so do the intestines, small and large.
Since the stomach doesn't also work to remove waste though, I'd say the answer is probably large intestine, which finishes the digestive process and removes waste material.

What is the significance of Carbon cycle on plants, animals, ocean, and forest.

Lena [83]

Answer:

Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals.
